Abstract

A water valve may comprise a valve shell, and a rotating base is installed in the valve shell. A lower end of the rotating base is sequentially connected to a driving valve piece and a fixed valve piece which are installed in the valve shell. A center of a top portion of the rotating base comprises a valve rod upwardly protruding out of the valve shell. The rotating base is configured to engage with the driving valve piece, and through operating the valve rod, the rotating base driven by the valve rod is adapted to drive and have synchronous rotation with the driving valve piece so as to change the relative positions between the driving valve piece and the fixed valve piece and then to control on/off operation of a faucet, ratio of hot and cold water and the amount of water flow.

Claims

1. A water valve comprising,

a valve shell, and a rotating base installed in the valve shell;

a lower end of the rotating base sequentially connected to a driving valve piece and a fixed valve piece, and the driving valve piece and the fixed valve piece installed in the valve shell;
